Abstract
溫室盆栽臺茶13號茶苗以神澤氏葉蟎：捕植蟎＝20 : 1之比例接種法拉斯捕植蟎或智利捕植蟎，接種法拉斯捕植蟎之處理在接種後第10天及第14天分別達到72.8％及88.6％之防治率，而接種智利捕植蟎之處理則有84.0％及99.1％之防治率，田間在青心烏龍茶園釋放此2種捕植蟎，均對神澤氏葉蟎有良好之抑制效果，尤其智利捕植蟎之效果更為迅速。而田間自然發生之溫氏捕植蟎其功效似遜於此2種捕植蟎。
Amblyseius fallacis and Phytoseiulus persimilis were introduced to potted tea plants in glasshouse at a ratio of one twentyth of Tetranychus kanzawai. Both phytoseiid predators showed effective in the control of T. kanzawai. Amblyseius fallacis gave 72.8% and 88.6% of control at the 10th and 14th day after release, respectively, and, P. persimilis acchieved 84.0% and 99.1% of control. In field trials, release of both species, especially P. persimilis, reduced the population of T. kanzawai to less than one spider mite per leaf. A natural population of A. womersleyi in the experimental tea field contributed partially to the reduction of the population of spider mites, but it seemed could not suppress the spider mite population alone.
